Texas Roadhouse onion blossom is the chain’s whole fried onion appetizer, listed on menus as the Cactus Blossom at $8.99 and about 2,250 calories for the full shareable order, served with a creamy Cajun Horseradish dipping sauce.
What the onion blossom actually is
The onion blossom is one large sweet onion, cut so the layers fan out into petals, battered and deep fried whole, then served upright with a cup of Cajun Horseradish sauce in the center. On the printed menu it appears as the Cactus Blossom under Starters, priced at $8.99. It arrives as a single shared plate, not a per-person portion.

Onion blossom price and portion
The verified menu listing puts the onion blossom at $8.99, which makes it one of the cheapest appetizers in the Starters section. Because Texas Roadhouse lets each franchise and region set its own pricing, expect the number on your local menu to land anywhere from about $8 to $11.
Here is how it sits against the rest of the appetizer lineup on the same verified listing:
| Appetizer | Price | Calories |
|---|---|---|
| Cactus Blossom (onion blossom) | $8.99 | 2,250 |
| Fried Pickles | $7.49 | 550 |
| Rattlesnake Bites | $9.49 | 560 |
| Twisted Mozzarella | $9.99 | 710 |
| Boneless Wings | $11.99 | 760 |
| Cheese Fries | $11.99 | 1,240 |
| Combo Appetizer | $12.99 | 920 |
There is only one size. No half order, no lunch-portion version, and it is not one of the two free sides that come with an entree. It is a separate line on the check every time.
What’s in it: the onion blossom sauce and ingredients
The onion blossom sauce is the Cajun Horseradish sauce named directly on the menu listing: a creamy, mayonnaise-style dip carrying horseradish heat and Cajun seasoning, pale orange to pink in color, served cold in a small cup at the center of the onion. That contrast of cold dip against hot fried onion is most of the appeal.
The onion itself is a sweet variety, cut so the root end stays intact and the layers separate into petals. It gets a seasoned flour or batter coating and goes straight into the fryer. The seasoning blend is proprietary, so nobody outside the kitchen can list it exactly, and any online copycat recipe claiming to be the real thing is a reconstruction rather than a leaked spec.
Two practical notes on the sauce. First, servers will usually bring a second cup free if you ask, which matters because the standard cup runs out well before the onion does. Second, if horseradish is not your thing, ask for ranch or barbecue sauce instead; those are stocked for other items and staff are generally happy to swap.
Allergen-wise, it is a battered item sharing fryer oil with other breaded foods, and the dip is dairy and egg based. Ask a manager for the current allergen sheet if that matters to you.
Calories and nutrition
The onion blossom is listed at roughly 2,250 calories for the full order including sauce, the highest single number in the appetizer section by a wide margin. Split four ways that is around 560 calories per person, which is a much more reasonable framing than the headline figure.
Fat and sodium are both high, as you would expect from a deep-fried onion with a mayonnaise-based dip. Texas Roadhouse prints calorie counts on menus in markets where posting is required, and publishes fuller nutrition data on its official site, so check there for grams of fat, carbs, and sodium rather than relying on secondhand numbers.
If you want the flavor without the full hit, order it for the table and pair it with a lighter entree such as grilled chicken or sirloin with green beans instead of steak fries. Nobody eats a whole onion blossom solo and finishes their steak.
How to order it well
Order it early. The onion blossom takes several minutes in the fryer, and it is meant to land while your free rolls and cinnamon butter are still hot. If you order it alongside your entrees, it can arrive too close to the main course.
Ask for it fresh if the restaurant is slow, since a blossom that has been sitting under a heat lamp loses its crunch fast. Ask for extra sauce up front rather than halfway through. And if you are a party of two, consider splitting it as your only appetizer, because it genuinely is a four-person plate.
For takeout, it travels worse than most items on the menu. Steam trapped in the container softens the batter within about ten minutes. If you are driving more than a short distance, crack the lid open in the car, or pick a sturdier travel item such as the rattlesnake bites instead.
Is it worth it, and how it compares
At $8.99 for a plate that feeds four, the onion blossom is the best cost-per-person appetizer on the menu. Compare it with the $11.99 cheese fries, which cost a third more, feed fewer people, and get soggy faster. Against the $9.49 rattlesnake bites, the blossom wins on value and sharing but loses on portion control, since bites are countable and a blossom is not.
The case against it is simple. It is one flavor, repeated, at very high calorie cost, and the last third of the onion is usually thicker, greasier petals near the core that nobody fights over. Groups of two are better off with fried pickles at $7.49. Groups of four or more get real value here.
Why the menu says Cactus Blossom, not onion blossom
Plenty of guests search for the onion blossom and then cannot find it on the menu. That is because Texas Roadhouse calls its version the Cactus Blossom. Outback Steakhouse uses the Bloomin’ Onion name, and the generic term for the whole category is a blooming onion. They are the same idea executed differently: whole fried onion, dipping sauce, different batter and seasoning at each chain.
If you order an onion blossom by name at Texas Roadhouse, your server will know exactly what you mean and ring in the Cactus Blossom. No need to memorize the menu wording.
Where this page is uncertain
This is an independent guide, not the restaurant. Prices and calorie counts come from verified location menus but shift by market, franchise, and season, so treat $8.99 as a reference point rather than a guarantee. Some locations run higher, particularly in high-cost metros and airport-adjacent sites.
Recipe details beyond what the menu states are not public. We describe the Cajun Horseradish sauce by its menu name and general character, not by a claimed ingredient list. Availability is broad but not universal, and limited-time or regional menu changes can affect any item. To confirm before you go, call your specific location or check the current menu on the official Texas Roadhouse site or app.
